Here we have an otto Link 8 with a serial number of the early Florida production.  These serial numbered pieces are either exactly the same as a FL double ring inside or extremely close to it.  They are extremely difficult to find in any condition, but good to original condition is next to impossible.  This one I was lucky to get on a trade.  It was a great piece to start with, but I have very gently optimized it by cleaning up the tip rail and balancing the rails only.  The piece has not been opened or radically altered from its original configuration.  It plays exceptionally well and just has a specifically great voice.
